Hell don't be screwed up about it. Bent ones are beautiful, different, fascinating and feel great when you are on the receiving end. And the other beauty is that when you get hard, you don't have the embarrassment of it sticking out and looking hard. Just looks like its naturally big because it hangs down like a banana.
I don't know if you're gay or straight and it doesn't matter. But years ago I had an Australian boyfriend, his cock was bent just like a banana, and taking a paper measure tape to it it was 29.5 cm top to base. He always moaned that he couldn't do anything with it because of the shape (he never complained about the size, like most big guys do - the shape was more of an issue to him). Well no. Yes, shagging in the normal position hurts a bit. But shag upside down so that it points the other way. He or she (whatever) will love it and it then follows the natural path of the inside of the vagina or the backside.
You should be proud of it and even flaunt it.
However, if it it so bent that it gets you down, there are operations available to straighten it out a bit. The doctors' parameters for accepting the operation are whether it is depressing you so much that it is affecting your life. Unless you're willing to pay for a cosmetic surgeon. Frankly why bother, when it gives so many people so much pleasure?
